Pathfinder

The Pathfinder!

Introducing the Pathfinder Rebreather.  The ultra lightweight travel-friendly closed circuit rebreather with ISCan Electronics. IScan™ is the next generation electronics developed by Innerspace System Corp to power the new Pathfinder rebreather. IScan is a Controller Area Network system based upon proven ISO standards used in the automotive aerospace and defense industries IScan is a digital network designed to allow independent devices to communicate and ISCan interact with each other.  Handsets, HUDs and various sensors can operate independently and in concert to increase safety, redundancy and to reduce single points of failure.

Overview:
1-Split shoulder lung system designed for water trapping and water expulsion and low resistive effort for hydrostatic lung loading
2-ISC Exclusive dual partitioned breathing loop protects the diver from caustic cocktails.
3-eCCR configuration with IScan electronics, HUD, and handset. Other optional electronics available
4-Expedient electronic field repairs. Diver can replace all electronic components themselves
5-Single oxygen supply cylinder with first stage assembly
6-Radial CO2 scrubber canister available in both Standard and CE
7-ISC Tetradon III BCD with optional vest, or plate and harness system options available
8-Mil spec build quality under ISO quality assurance program
9-The Pathfinder Rebreather system is compatible with Megalodon CCR breathing loop
10-Two-cylinder capability utilizing ISC Shadow Mount system.
11-System supports cylinder sizes up to 19cuft/3L

Training:

New ISC PATHFINDER divers undergo a 3 to 5 day training course using a single or multi-gas dive computer for decompression management.
The PATHFINDER system is used primarily with one oxygen cylinder mounted on the unit. The diluent cylinder is mounted as a stage bottle to supply diluent, BCD operation and bailout. This eases weight and complexity, as the diver does not need two cylinders mounted on the back of the CCR to operate the PATHFINDER.

System Specifications:

Weight 34 lbs/15.5kg (lightest configuration).
Size: 18.5”/45cm x 12.5”/31.75cm x 6”/15.25cm.

IScan Information

IScan products are designed to perform reliability in “noisy” environments.
The messaging protocol was developed in cooperation with Shearwater Research to allow our devices to communicate and work together with the Shearwater Predator.
All controller functions are safely contained in the head
Handsets, HUDS and controllers calibrate independently
Modular design allows devices to be interchanged in the field with a few simple tolos
Firmware can be updated via Bluetooth connectivity
IScan has been tested to all standards required by EN14143 for CE Certification by accredited independent labs
